Radiative Penguin Decays from BABAR

چکیده

Electroweak penguin decays provide a promising hunting ground for Physics beyond the Standard Model (SM). The decay B → Xsγ, which proceeds through an electromagnetic penguin loop, already provides stringent constraints on the supersymmetric (SUSY) parameter space [ 1]. The present data samples of ∼ 1 × 108BB̄ events allow to explore radiative penguin decays with branching fractions of the order of 10−6 or less. In this brief report we discuss a study of B → K(∗)l+l− decay modes and a search for B → ρ(ω)γ decays.

Rare Hadronic and Radiative Penguin B Decays at BABAR

We report recent results in the study of rare hadronic and radiative penguin decays of B mesons. These results are based on a sample of 23 million BB pairs collected by the BABAR Collaboration at the SLAC PEP-II ee B Factory. Contributed to the Proceedings of the 5 KEK Topical Conference: Frontiers In Flavor Physics (KEKTC5), 20-22 Nov 2001, Tsukuba, Ibaraki, Japan. Stanford Linear Accelerator ...

Radiative Penguin Decays at the B Factories

In this article, I review the most recent results in radiative penguin decays from the B factories Belle and BABAR. Most notably, I will talk about the recent new observations in the decays B → (ρ/ω) γ, a new analysis technique in b → sγ, and first measurements of radiative penguin decays in the B s meson system. Finally, I will summarize the current status and future prospects of radiative pen...

Radiative b → d Penguins

This article gives an overview of the recent searches and measurements of b → d penguin transitions with the BaBar experiment. The branching fraction of these decays in the Standard Model (SM) is expected to be a factor of 10 or more lower than the corresponding b → s penguin transitions, but a deviation from the SM prediction would be an equally striking sign of new physics. The exclusive deca...
